丙丁酚对载脂蛋白E~(-/-)小鼠主动脉粥样硬化病变及病变处凝集素样氧化型低密度脂蛋白受体1表达的影响

目的观察丙丁酚对载脂蛋白E-/-小鼠主动脉粥样硬化斑块形成及主动脉凝集素样氧化型低密度脂蛋白受体1表达的影响,以探讨丙丁酚调节血脂以外的可能的抗动脉粥样硬化作用机制。方法将21只4周龄的雄性载脂蛋白E-/-小鼠随机分成基础饮食对照组、高脂饮食对照组和高脂饮食加丙丁酚组     

Cardiac tamponade due to intrapericardial rupture of an amebic liver abscess

Pericardial abscess is rare in healthy individuals, especially the amebic type. We report a case of pericardial abscess and cardiac tamponade due to intrapericardial rupture of an amebic liver abscess. A 31-year old Japanese male complained of fever to a local hospital. A liver mass was discovered in his left hepatic lobe by an abdominal echogram. He was referred to the internal department of our hospital and was treated with quinolone antibiotics. Two weeks after medication, he suddenly complained of epigastralgia and severe orthopnea and was admitted. Abdominal computed tomographic scan showed an enlarged liver mass, and massive pericardial effusion suggested cardiac tamponade. He underwent an emergency subxiphoid partial pericardiectomy under local anesthesia. 1,000 ml of light brownish fluid was removed and his condition improved. Although no ameba was cultivated from the pus, the amebic serological test was positive. Metronidazole was administered and the patients was discharged 31 days after surgery.
